    ® MICRO Appendix C CE Labeling What is CE Labeling? The purpose of CE labeling is to avoid technical obstacles to trade within EFTA and the EU. The EU has introduced the CE label as a simple way of showing whether a product complies with the relevant EU directives.
  • Page 80 It must be noted that the responsibility for the final EMC properties of the appliance, system or installation rests with the installer. As a aid to the installer, Danfoss has prepared EMC installation guidelines for the Power Drive System. The standards and test levels stated for Power Drive Systems are complied with, provided the right EMC-correct instructions for installation have been followed.
  • Page 81 ® MICRO General Aspects of EMC Emissions Electrical interference at frequencies in the range 150 kHz to 30 MHz are cableborne. Airborne interference from the drive system in the range 30 MHz to 1 GHz is generated from the inverter, the motor cable and the motor. As the drawing below shows, capacitive currents in the motor cable together with a high dV/dt from the motor voltage generate leakage currents.
  • Page 82 ® MICRO EMC-correct Electrical Installation General points to be observed to ensure EMC-correct electrical installation: - Use only shielded motor cables and shielded control cables. NOTE: Suggested shielded cable type, like that supplied by Southwire. - Connect the shield to ground at both ends. - PG Cable Glands, of the type shown below, are recommended.
